Expression

The main problem in the critical analysis of the theoretical interpretations of the concept of expression in architecture, lies in the fact that the concept of expression is used in different ways in different fields of science and art. Regarding the concept of expression, the following interpretations can often be found:

an activity or way of transforming an idea into words;
showing emotions, feelings etc.;[1]
conveying emotions by way of music, images etc.;
facial expression showing mood or emotion;
choice of words, phrases, syntax, intonation etc., in communication;[2]
a specific phrase commonly used to express something etc.
In the widest sense, the concept of expression refers to the activity undertaken with a specific intention. However, what is the aim of expressing something will depend on the field in which the term is used.[3]
